How long do ventilations last for infants during CPR?

During CPR for infants, each ventilation should last about 1 second. This duration is crucial because it allows sufficient time for the air to be delivered into the infant’s lungs while ensuring that the chest visibly rises. This visible chest rise indicates that the air is effectively entering the lungs, which is vital for delivering oxygen to the infant's body.

Ventilations for infants must be gentle and should not be forceful, as their lungs are delicate and can be easily over-inflated or damaged if too much air is forced in too quickly. Maintaining the proper duration helps prevent complications and ensures that the ventilations are effective. The one-second guideline strikes a balance between being long enough to effectively fill the lungs and short enough to avoid causing harm.
